a CRUMB-REMOVER.

SIECIFICATION forming part of Letters Patent No. 536,050; dated March19, 1895. Application filed September 20, 1894. Serial No. 523,622. (Nomodel.)

To all whom it may concern.-

Be it known that 1, JAMES B. O. SHEVILL,

.of the city, county, and State of New York,

have invented a new and Improved Crumb Remover, of which the followingis a full, clear, and exact description.

My invention is an improvement in that class of crumb-removers for tableuse which are provided with a revoluble brush arranged in front of acrumb-receiving pocket, or 001 partment.

My device comprises a longitudinally-slotted casing, which incloses thebrush,together' with its operating gearing, and a handle which ispivoted to the top of the casing and arranged in alignment with it, andlikewise so constructed as to provide stops that limit the Verticalmovement or oscillation of the handle, relative to the casing, ashereinafter more fully set forth.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the improvement. Fig. 2 is a rear sideelevation of the same. Fig. 3 is asectional side elevation of the same.Fig. 4 is a cross section of the same on the line 4-4= of Fig. 2. Fig. 5is an inverted plan View of the same; and Fig. 6 is a transverse sectionof the same on the line 66 of Fig. 2. I I v The improved crumb removeris provided with a casing A, made approximately semicircular in crosssection, as indicated in Fig. 4:, the casing having the ends A, .A andtransverse partitions A A arranged near the said ends A, A respectively,so as to form compartments therewith for the driving mechanism of theremover. The partitions A A are connected to the ends A, A at theirbottom parts, by the plates A as plainly indicated in Fig. 5, and thesaid partitions are rigidly connected with each other at their ends andat their bottom edges by the bottom plate A See Fig. 5. On the rear edgeof the latter is hinged at A a door A", provided with a suitable catch Afor locking the said door to the rear end of the casing, and permittingopening of the said door to remove the crumbs gathered by the 'brush, ashereinafter more g fully described.

In the spaces between the partitions A ,A and the ends A, A of thecasing A are arranged driving wheels B, preferably covered at theirperipheries by a rubber band which extends upon the rim of the wheelsand below the surface of the bottom plate A, to support the casing abovethe table cloth, over which the remover is moved to gather up thecrumbs.

The wheels B are journal'ed on studs 0, supported in the partitions A Aand each of the wheels B is formed with an internal gear B in mesh witha pinion D secured on the respective outer ends of'the shaft E, of therevoluble brush F, said shaft E being journaled in the partitions A A.The brush F has its bristles preferably set spirally on the hub of thebrush, as is plainly illustrated in Figs. 3 and 5, but I do not limitmyself to this special construction of the revoluble brush.

By forming an opening in the casing in front of the lower part of thebrush and by cutting away part of the lower front edge of the casing andpart of the bottom, the said revoluble brush readily engages, sweeps upand removes the crumbs in the path of the casing, as the latter iswheeled over the table cloth. By the arrangements described, noadditional trailing or supporting wheels are required.

The brush sweeps the crumbs upward over the curved bottom plate A (Fig.4), into the pocket in rear of the latter, and any crumbs adhering tothe brush are removed by the scraper, H, attached to the top of thecasing, A. The attachment and arrangement of the handle J, areasfollows: The handle is pivoted to the top of the casing, in alignmentwith it, and projects beyond one of its ends, so that it may beconveniently grasped and held for the purpose of manipulating thecrumb-remover proper. The inner endof the handle shank, J, is slightlycurved, and pivoted between lugs that project from a plate, I, attachedto the top of the casing at a point equidistant from the ends of thesame. The pivotal point is slightly removed from the end of the shank,J, and also from the plate, I, so as to provide a narrow space betweenthe latter and the shank. It is apparent that, by this construction andarrangement, the vertical movement or oscillation of the handle, J,relative to the casing, A, is limited by contact of the shank with saidplate, I, at a point on each side of the pivot. Thus, the upwardmovement of the handle, J, is limited by contact of its free end withsaid plate, as shown by dotted lines Fig. 2, and its downward movementis limited by contact of the body of the shank with said plate, on theinner side of the pivot, as shown by full lines, Fig. 2. Practically,therefore, the movement of the handle and easing relative to each otheris limited by stops arranged adjacent to the pivot of the former.

The crumb-remover may be swept over a table like the hand -brushcommonly used, without any difficulty in keeping the casing and brushincontact with the cloth or other surface; and,when the device is liftedfrom the table, it may be held and carried horizontally,

from the free end of the handle shank, as

shown, whereby the vertical movement of the handle relative to thecasing is 1i mited as specified.
